Answer:
y=6*x+101
Step-by-step explanation:
Slope intercept form is y=mx+n, where m is the slope and n is the intercept.
Substituing in that equation the two points we get two different expressions. Now we have to solve a 2x2 system of equations.
I decide to solve it through substraction (literally one expression minus the other). That way we cancel out the n and obtain the value of m.
Now that we have m we plug in the value of m in one of the expressions to obtain the value of n.
To express the final equation we just plug in the values of m and n in the expression y=mx+n!

Step-by-step explanation:
A = πr² ← r is the radius and r = d ← d is the diameter
Hence
π ( d)² = A, that is
= A ( multiply both sides by 4 )
d²π = 4A ( divide both sides by π )
d² = ( take the square root of both sides )
d =
